In the Buck converter tutorial block, we show how to use the O2 as a buck converter from open-loop to closed-loop voltage mode control.

• Micro-grid 1 - Solar Home System - You will setup the O2 as an independent buck-boost and buck converter on separate closed operation. The high-voltage side will be connected to a PV module, leg 1 will be connected to a battery and leg 2 will be connected to a load. Leg 1 will have its PID driving the current on the low-voltage side (charge or discharge mode). Leg 2 will have its PID driving the voltage on the low-voltage side.
• Micro-grid 2 - Droop control Grid - Using two O2 converters using the same code from the previous tutorial, you will deploy a droop control algorithm that will allow to control the power flow between modules with no communication.
• Micro-grid 3 - Peer-to-peer power flow control - Using the same setup from the previous tutorial, you will add a CAN based communication that will allow the modules to coordinate their power flow and add intelligence to the micro-grid.
